which expression is equivalent to 7a-8-12a+4​

Answer:

The linear function is [tex]y = -3x + 2[/tex]

Step-by-step explanation:

A linear function has the following format:

[tex]y = mx + b[/tex]

In which m is the slope and b is the y-intercept(the value of y when x = 0).

In the table, we have that when x = 0, y = 2

This means that [tex]b = 2[/tex]. So

[tex]y = mx + 2[/tex]

Finding the slope:

We take two points, and the slope is given by the change in y divided by the change in x.

Points (0,2) and (1,-1)

Change in y: -1 - 2 = -3

Change in x: 1 - 0 = 1

Slope: [tex]m = \frac{-3}{1} = -3[/tex]

So

[tex]y = -3x + 2[/tex]

Answer:I think ia 18

Step-by-step explanation:

The number of small boxes the bakery fills in a day = 183 cookies.

The total number of cookies the bakery makes in a day =

1,650 cookies.

The number of cookies found in big box = 24 cookies

The number of cookies found in small box = 3 cookies

To find the number of small boxes that was fill would be to share 1,650 cookies in the ratio of 24 : 3

The total amount of cookies each box can hold = 24+3=27

Divide the amount by the total quantity of cookies=

1,650/27 = 61 cookies

Each number of the boxes should be multiplied by one part ; small boxes × 61 cookies

= 3 × 61

= 183 cookies.

Therefore, the number of small boxes the bakery fills in a day = 183 cookies.

The value of x in expression is,

⇒ x = [- 4, 1, - 2, - 7]

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

The expression is,

[-1, -2, 4, 8] + x = [-5,- 1, 2, 1]

Now, We can simplify as;

x = [- 5, - 1, 2, 1] - [ - 1, - 2, 4, 8]

x = [- 4, 1, - 2, - 7]

Thus, The value of x in expression is,

⇒ x = [- 4, 1, - 2, - 7]

Answer:

1. Mode = 7

2. Range = 8

Step-by-step explanation:

The following set of data were obtained from the question:

4, 6, 5, 9, 3, 2, 7, 7, 1, 8

Mode =?

Range =?

1. Determination of the mode of the data.

Mode is simply defined as the mark (score) with the highest frequency. Thus we can obtain the mode as follow:

Scores >>>>>>> Frequency

4 >>>>>>>>>>>> 1

6 >>>>>>>>>>>> 1

5 >>>>>>>>>>>> 1

9 >>>>>>>>>>>> 1

3 >>>>>>>>>>>> 1

2 >>>>>>>>>>>> 1

7 >>>>>>>>>>>> 2

1 >>>>>>>>>>>> 1

8 >>>>>>>>>>>> 1

From the above illustration, we can see that the mark 7 has the highest frequency. Therefore, 7 is the mode of the data .

2. Determination of the range of the data.

Range of a given data is simply obtained by calculating the difference between the highest and the lowest score. The range can be obtained as follow:

Highest score = 9

Lowest score = 1

Range = Highest – Lowest

Range = 9 – 1

Range = 8

Step-by-step explanation:

Answer:

a)

Therefore to compare this data effectively using the rates per driver is better off like for people who do not smoke their rate will be = 59 / 452 = 13.1% while for smokers of 61+ times = 50 / 156 = 32.1% and this rate will show clearly tat more accidents where caused by people who smoked 51+ times hence it should be used for graphical representation

b) attached below

Step-by-step explanation:

A) A  useful graph is must compare rates rather than counts of accidents in the four marijuana use classes

Using the rates on a graph is better for reference like saying; that 50 crashes were caused by those who smoke 51+ times and 59 crashes is caused by those who never smoke this statistics makes it seem like smoking has no effect on the amount of accidents

Therefore to compare this data effectively using the rates per driver is better off like for people who do not smoke their rate will be = 59 / 452 = 13.1% while for smokers of 61+ times = 50 / 156 = 32.1% and this rate will show clearly tat more accidents where caused by people who smoked 51+ times hence it should be used for graphical representation

B) accident rate for Non-smokers

 = (59/452) * 100 = 13.05

accident rate for smokers between 1-10 times

= ( 36/ 229 ) * 100 = 15.72

accidents rate for smokers between 11 - 50 times

=  ( 15/50 ) * 100 = 21.42

accidents rate for smokers 51+

 =  ( 50 / 156 ) * 100 = 32.05

Answer:

2.7 mpg less than Evan's

Step-by-step explanation:

Riley gets 430.1 / 11 = 39.1 mpg

Evan gets 418 / 10 = 41.8 mpg

41.8 - 39.1 = 2.7

9514 1404 393

Answer:

  2.7, less

Step-by-step explanation:

To find miles per gallon (MPG), divide miles by gallons.

  Riley's car:

     (430.1 mi)/(11 gal) = 39.1 mi/gal

  Evan's car:

     (418 mi)/(10 gal) = 41.8 mi/gal

__

Then the difference is ...

  41.8 -39.1 = 2.7 . . . miles per gallon

We note that Riley's MPG is less than Evan's, so we can write ...

  Riley's car gets 2.7 miles per gallon less than Evan's car.

Answer:

About 34.5 which you can round to 35

Step-by-step explanation:

First you find the hypotenuse of 30 and 16 which is 34

Then the hypotenuse of 34 and 6 which is about 34.5

The length of the hose from the top corner to the bottom corner farthest away will be 34.5 feet

A rectangular prism is a 3-D figure, which has 6 faces, 8 vertices and 12 edges. All of the faces will be in rectangular shape.

Rectangular prism has three dimensions, namely, length, width and height.

Length of the swimming pool = 30 feet

Width of the swimming pool = 16 feet

Height of the swimming pool = 6 feet

We have to find the length of the hose from the top corner to the bottom corner farthest away.

For that first we have to find the length of the hypotenuse of the triangle with base = 30 feet and altitude = 16 feet

= √(30² + 16²)

= 34 feet

Now, we have to find the hypotenuse of the triangle with base = 34 feet and altitude = 6 feet.

= √(34² + 6²)

= 34.5 feet

Hence the length of the hose from the top corner to the bottom corner farthest away is 34.5 feet.
